IETF 98 Network Information – Chicago, IL USA

Terminal Room

The Terminal Room is located in Vevey 3 in the Event Center on the 2nd Floor. The Terminal Room is open 24 hours each day beginning Sunday, 26 March, 2017 at 16:00 and ending on Friday, 31 March, 2017 at 15:00. A help desk is provided and the hours are listed below. The room itself consists of approximately 50 seats, providing some wired access and 120v power ports. There is also an HP Officejet Pro 6978 printer available.

Please note that this terminal room has no terminals, PCs, or other user-accessible machines. It is simply a place to get power, wired and wifi Internet access, help desk support, print documents, and/or work quietly.

When using the Ethernet connections in the Terminal Room, IPv4 addressing is provided via DHCP. Please use Stateless Auto-configuration for IPv6 (SLAAC). A DHCPv6 server or RDNSS will provide network information. To cut down on the mess, ethernet cables have not been installed to every seat in the Terminal Room. If you need a cable, please ask at the Help Desk.

Please note that at the request of the IETF Chair, demonstrations are no longer permitted in the Terminal Room.

If you have an existing account on ​https://tools.ietf.org you can use your established credentials (email address and tools password) to log in.

Send an email to tickets @ meeting.ietf.org with as much detail regarding your issue and configuration as possible.

If you're on site and need direct network assistance (i.e - you have no network) please go to the Help Desk, which is located in the Terminal Room.

You can also use trac to review outstanding tickets before reporting an issue or to update outstanding tickets.

The Secretariat also maintains a ticket system for the reporting of meeting issues. Please send
mail to: mtd @ietf.org to report a problem. The Secretariat is responsible for addressing issues with:

A/V in meeting rooms

Beverage and food

Jabber

Projectors

Temperature fluctuation

External Connectivity

The IETF 98 network connects to the Internet via multiple 1Gb/s uplinks, graciously donated by Comcast and AT&T, in both the Swissôtel and the Fairmont. The IETF uses 2001:67c:370::/48 for IPv6 and 31.133.128.0/18 and 31.130.224.0/20 for IPv4. We are supplying bandwidth for the conference space, as well as wireless connections in the guest rooms in both hotels.

Meeting Room Wireless

An 802.11 a/g/n/ac wireless network is provided throughout the venue on both the 2.4 and 5 GHz bands, in conjunction with IPv4 and IPv6 addressing options.

The main “ietf” wireless network is encrypted; make sure you enter ietf for both the username and password.

Here’s a quick summary of the network layout:

All networks marked as encrypted will offer layer 2 security. This is done using WPA2 enterprise with 802.1X (PEAP or TTLS) authentication and AES encryption. As usual, we are all using the same credentials (user “ietf”, password “ietf”), yet each user will get unique session encryption keys. Stefan Winter has kindly provided signed profiles that will supply the appropriate SSL certs: ​https://802.1x-config.org/?idp=137&profile=101

Guest Room and Public Space Access

The IETF Network is being extended to the guest rooms and public spaces throughout the Swissotel and it's sister hotel, the Fairmont. This is being delivered via the hotel's wireless infrastructure as an additional SSID, "ietf-hotel" in the Swissôtel and "ietf-fairmont" in the Fairmont. Due to infrastructure limitations in the Swissôtel, wired ethernet is available in roughly 1 in 3 guest rooms, spread throughout the hotel (rooms that host a wireless access point also have a wired port). There is no wired ethernet in the Fairmont.

Note If you have performance issues with this network, please let us know. Please note though, that while we are using the IETF meeting network for Internet connectivity, we are using the hotel's infrastructure for delivery to the guest rooms and public space, so there are limits to the improvements we can effect.

Support

If you have trouble using the guest room and public space SSID "ietf-hotel" or "ietf-fairmont", please contact us in the Terminal Room (Vevey 3) or via tickets @ meeting.ietf.org and we’ll be glad to help!

Printing

There is a printer in the Terminal Room and is available to all IETF users. The printer is an HP OfficeJet Pro 6978 and is accessible via LPD, Bonjour, standard TCP/IP on port 9100. The hostname for it is term-printer.meeting.ietf.org. This printer is compatible with the OfficeJet Pro 8620 we've used in previous meetings, so if you were able to use the printers previously, this one should "just work".

Place pages to be scanned face-up in the page feeder on top of the printer.

Press "Start Scan" on the web page.

Once the Scan has completed a window to the right will display the PDF contents of the scan.

Thanks

The terminal room and IETF network are made possible by the generous contributions by a number of companies and by the tireless efforts of our volunteer team. If you see any of these people in the halls, please be sure to thank them for all their work!
